As a best practice, you may include only the MAJOR version number no matter the versioning technique used. What is REST REST is all about the representational state transfer of an object. It allows us to easily implement versioning in our ASP.NET Core applications with a few configuration lines. breaks backward compatibility, z is incremented. In this next part, I'd like to share some best practices for API versioning - a topic that comes up quite often with every customer as it is one of the key concerns when implementing API gateways. 21 August 2016 on REST API, REST API Management, Architecture, REST API Versioning.
